Abstract

The improved single-exposure phase-shifting digital holography using a
random-phase reference wave is
proposed. The algorithm for obtaining a complex amplitude of an object wave is
improved. In the proposed
algorithm, the reference wave is treated as not a random-phase but a
random-complex amplitude.
Therefore, the algorithm uses proper amplitude information of the reference
wave. Both numerical simulations
and experimental results are given to confirm the effectiveness of the proposed
algorithm.
